Geospatial Data for Exploration & Geology

Regional Topography

User-ready topography for exploration planning
When geologists are planning new exploration programs, it is crucial to have access to reliable topography of the area. But when these areas are remote or large, getting reliable topography can be difficult, potentially delaying a project at the start.

PhotoSat’s Regional Topography package equips exploration professionals with reliable topographic data, without the need for ground control or site access.

Key applications:
  • 3D modelling
  • Exploration program planning
  • Geological targeting
  • Logistical coordination
Elevation grid formats:
File Format(s): ASCII, CSV, DWG, DXF, ECW, ERS, LAS, TIF, and XML.

Thinned Grid formats are available to reduce file size for projects over low-grade slopes.
Technical Specifications:
